Guy,
If I remembered correctly, you need not have the command "atm classic-ip-extens
ions BFI" unless you have redundant arp servers.

Subject: ATM classical IP
Sorry for all the ATM questions, I have some virtual rack time today and I
am trying to get the most out of it. I have the classical IP working, but I
want to make sure it is working correctly. I posted my configs below, I
would appreciate if someone could take a look at them and let me know if it
looks correct. When setting up classical ip, you specify an arp server.
One of the routers is the arp server in my config, when I do a show atm
arp-server I see all the mappings, but on the client when I do a show atm
arp-server, I don't see anything. Is this because it is not the arp server?
I think that is the case, I just want to make sure I have this nailed down.
Also, IPX doesn't work with this correct? Thanks.
